Insane in the membrane! I am trying to remove the faceplate on my amp to recap one of the boards behind it and came across this muting button that needs to be removed in order to get the plate off and access the board underneath. The button appears to be held in place or mounted with a very supple clear silicone or rubber plug. So far, I've just been able to remove all the knobs on the faceplate by pulling them straight off, but this one is different. I tried pulling it straight off like the others, but it didn't give and just strettcchheedd. Since it appears very rubbery and soft, I don't want to damage or tear it by ripping it straight off. Any help or recommendations how to get this membrane off safely?
